General Information: Founded in 1955, the family-owned manufacturer markets wood, vinyl and fiberglass windows and patio doors under the brand names of Weather Shield, Visions and Crestline; and entry doors under the Peachtree brand name. Based in Medford, Wis., the company has invested time and resources into product development of late, introducing three new Weather Shield product lines, including the Aspire Series of vinyl-clad wood windows and patio doors in mid-2012, and the forthcoming aluminum-clad wood lines, the Signature Series and the Premium Series, said to raise the bar on thermal performance, energy efficiency and aesthetics. The company also closed a manufacturing facility in Mosinee, Wis., in 2012, moving capacity to other manufacturing facilities in Medford, Ladysmith and Park Falls, Wis.
